)

Parameters

bbox
Type: Telogis.GeoBaseBoundingBox
The BoundingBox representing the area to be queried.
type
Type: Telogis.GeoBaseStreetType
The StreetType that should be matched.

Return Value

An array of Streets matching the specified type.

This method also matches Streets that pass through bbox and continue outside its area.
Further, Streets with BoundingBoxes that intersect bbox will also be returned by this method, thus it is possible that streets will be returned that appear to lie outside rect.

Examples
C#
Copy
   // Create a BoundingBox enclosing and intersecting with the streets to query
   BoundingBox queryBox = new BoundingBox(new LatLon(33.634706, -117.900585), 
       new LatLon(33.633433, -117.899539));

// Create a cancellation token
var token = new CancellationToken();

   // Create the QueryStreets array. In this case specifying a StreetType of 'STREETS'
   Street[] queryStreets = DataQuery.QueryStreets(queryBox, StreetType.STREETS, token);

   // Write out the results
   string output = "Found " + queryStreets.Length + " streets in the BoundingBox: ";
   for (int i = 0; i < queryStreets.Length; i++) {
       output += queryStreets[i].ToString() + ", ";
   }
   Console.WriteLine(output);
   // Found 10 streets in the BoundingBox: Diana Ln, Deborah Ln, Sylvia Ln, Priscilla 
   // Ln, Beryl Ln, Highland Dr, Santiago Dr, Tustin Ave, Santa Ana Ave, Orange Ave,
